I seems that the exception is not related to Find in Projects. You have probably changed Logger level for parsing. Is the exception thrown if the level is not changed (the default one is used)?
(In reply to comment #2) > You have probably changed Logger level for parsing. Is the exception thrown if > the level is not changed (the default one is used)? I'm sorry, my mistake, I checked the IDE Log again and all messages have level INFO, so the level was not changed. But I still cannot find cause of the OutOfMemoryError. Maybe indexing of a large number of files. Closing as incomplete. Please reopen if you can add more information. Thank you.
